type descriptions for each framework are explained by whether an object is toll-free bridged, and what object is bridged. For further information, please read the core Foundation Framework reference. Objective-c the transition between the pointer and the corefoundation pointer Arc only manages objective-c pointers (retain, release, autorelease), does not manage corefoundation pointers, and CF pointers are managed manually by manual cfretain and cfr
